New polymethine cyanine dyes covering hepta methine cyanine dyes (tricarbocyanine dyes) and nonamethine cyanine dyes (tetracarbocyanine dyes) derived from the nucleus benzo[(2,3-b)benzoxazine; (2′,3′-b’)furo (3,2- d)pyrazole] were designed and prepared using novel synthetic strategy. Electronic transitions for all the synthesized cyanine dyes was determined and evaluated through investigating their electronic visible absorption spectra in 95% ethanol solution The dyes were thought to be better electronic transitions when they absorb light at higher wavelength bands (bathochromic shifted and/or red shifted dyes). Consequently, the electronic transitions of the dyes decreases when they absorb light at lower wavelength bands (hypsochromic shifted and/or blue shifted dyes). Solvatochromic and/or halochromic evaluation for some selected dyes was carried out and determined through examining their electronic visible absorption spectra in 6 (six) pure solvents having different polarities [water (78.54), DMF (36.70), ethanol (24.3), chloroform (4.806), carbontetrachloride (2.238) and dioxane (2.209)] and/or in 8 (eight) aqueous universal buffer solutions owing varied pH values (1.99, 2.99, 4.30, 6.87, 7.96, 8.91, 10.55 and 12.04 units), resp. Structural characterization and determination was carried out via elemental anal., visible, mass, IR and ¹HNMR spectroscopic data.

Krieg, R. published the artcileOptimization of heterocyclic 4-hydroxystyryl derivatives for histological localization of endogenous and immunobound peroxidase activity, Computed Properties of 606-55-3, the publication is Biotechnic & Histochemistry (2007), 82(4-5), 235-262, database is CAplus and MEDLINE.

Assisted by the development of light excitation and measuring techniques and the com. availability of highly sensitive equipment, luminescent labels are sensitive detection tools for life sciences research. By contrast to a wide variety of well established chromogenic techniques, fluorescent labels for detecting peroxidase (PO) have been confined to only a few substrates. We describe here novel fluorescent substrates of PO derived from heterocyclic 4-hydroxy styrenes as useful tools for detecting endogenous and exogenous targets in fixed cells and tissues. Excellent localization, high staining sensitivity, outstanding photostability, and exceptionally low background staining were achieved by optimizing the substrate through chem. synthesis. Structure/staining behavior relationships are discussed. By contrast to tyramine-fluorochrome conjugates employed in the catalyzed reporter deposition (CARD) technique, reporting and anchoring functions are no longer separated Consequently, enzymic crosslinking of the substrate yields an altered fluorochrome with different properties. Spectral properties and anchoring capability are interdependent and influenced by environmental effects and pH. We screened overall staining capability of 4-hydroxy styryl derivatives using an iterative semi-empirical approach, and ascertained optimal substitution patterns for high PO staining specificity and high fluorescence response. Reliable staining performance was achieved with alkyl chains of short or medium length at the pos. charged nitrogen, whereas introducing polar groups often impaired the staining specificity of PO. Catalytic crosslinking of heterocyclic 4-hydroxy-styryl derivatives is a promising approach for permanent fluorescent staining of PO in fixed cells and tissues, and complements the CARD technique. Histochem. and immunohistochem. applications are presented using conventional and confocal fluorescence microscopes with different excitation sources. Spectral properties of selected stains are discussed. Novel stains also are of potential interest as ‘reactive-tracers’ for living cells under multi-photon laser excitation conditions, because they exhibit pronounced nonlinear optical properties.
